Someone needs to come up with a legit Maul build that works for pvp using legitimate items, too. I've done a lot of thinking on "HOW THE HECK IS MAUL GONNA POSSIBLY WORK IN DUELZ" and I've come up with a few thoughts, but basically I come to the same conclusion.... as a skill, it doesn't:
1) ar bonus is too low, compared to fireclaw
2) you'd have to hit like 15 times to reach peak damage, where if u just put 1 pt into the skill you'd have the same damage accumulated by the end of the duel as you would maxing it. So basically, that's a LOT of points to waste JUST for the ar bonus for dueling.
The only item setup that I see working would be using 40ias Grief PB with Fortitude and SS (phoenix vs casters?), then with 15%oias you'd swing a healthy 7 frames... sry but I think its the only item that competes in damage and speed.
Some different ideas for skill placements might be like:
20 oak/20 HoW (if needed ar)
~40 cyclone synergies
20 werebear (for %damage/defense)
~40 fireclaw synergies
Both setups would make a lot more sense than by wasting 20 full points in maul for dueling
